IMX28 VDDIO voltage differs from setting

The iMX28 generated VDDIO is on all of our boards 3.4V, although the 8004_4060(hex) register is set via software to 0004230a(hex).

VDDA and VDDD however have exactly the voltage that I expect based on the respective register values.

 

Does anybody know where this VDDIO deviation come from? Thank you.
